Title: Television signal processing circuit
Inventor: SAKURABA NOBUTOSHI
IPC: H04N5/14
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce the internal power consumption of a TV signal processing circuit or a D/A converter when effective bit length is short as compared with a case when it is long by executing control so as to permit one or plural bits within the lower side bits of a signal which is inputted to a digital signal processing block or the D/A converter to be 'L'-fixed or 'H'-fixed. SOLUTION: A TV signal inputted to an A/D converter 2 is converted to a 12 bit-parallel digital signal. The 10 high-order side bits in the digital signal are inputted to an arithmetic circuit 4 and the two low-order side bits are inputted to the arithmetic circuit 4 by way of an AND gate circuit 9. When effective bit length is made to be max. so as to execute a signal processing, a control signal 'H' is inputted to a control terminal 13 and the signal is made to pass through AND gates 9-12. When effective bit length is reduced so as to execute the signal processing, the control signal is made to be 'L'. Thus, the power consumption of the respective circuits are reduced in accordance with decreased portions in the time of signal level change-over operations.

Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To prevent a high luminance part from being white and to set a main object to appropriate brightness by relating and deciding an exposure and gradation based on the luminance distribution of images picked up by reference exposure conditions for preliminary image pickup. SOLUTION: For image signals converted in a CDD 104, a luminance processing and a chrominance processing are executed in a process circuit 107 and they are outputted to an output circuit 113 as digital video signals composed of luminance signals and color difference signals. A main CPU 110 generates the histogram of the luminance distribution from the digital value of the luminance signals for respective picture elements image picked up by the reference exposure conditions for the preliminary image pickup. In the luminance processing in the process circuit 107, the histogram of the luminance distribution is referred to, and when a luminance distribution width is excessive for instance, the exposure at the time of photographing smaller than the preliminary image pickup exposure conditions is decided.  Further, estimated luminance distribution is generated based on the exposure in photographing and gradation characteristics are decided so as to turn the luminance area of a high distribution frequency to a reference luminance value.

Title: Molding die for optical element
Inventor: YONEDA YASUHIRO
IPC: C03B11/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To obtain an optical element having high dimensional accuracy without causing sink on the surface by using such molding die materials for the molding dies to press mold an optical element that the thermal conductivity of the one molding die differs by a specified value from that of the other molding die. SOLUTION: A glass raw material 3 softened by heating is press formed into a desired shape in a pair of dies for an optical element. Such die materials are used that the thermal conductivity of the one molding die 1 differs by >=40W/m.K from that of the other molding die 2. When the glass raw material softened by heating is to be press molded, the cooling rate of the glass raw material is slow on the part in contact with the molding die having the smaller thermal conductivity than the part in contact with the molding die having the larger thermal conductivity. Therefore, the part with a low cooling rate is shifted from the center of the glass raw material to the surface part where the surface is in contact with the molding die having the smaller thermal conductivity.  The part which solidifies last is the surface part of the optical element, which does not generate a tensile effect to sink the surface of the optical element.

Abstract: PURPOSE:To restore a line quickly by providing a line monitor means for generating a fault signal to a line control section and providing a stop means for detecting the fault signal to stop the use of the line of the terminal equipment to each terminal equipment. CONSTITUTION:If a fault takes place in a terminal equipment and a 1st output- enable signal from a terminal control section 16 remains outputted, a line monitor means 12 of the line control section 10 sends a consecutive 0s signal as a fault signal. Then a fault signal detector 17 of the terminal equipment A receives the fault signal, a 2nd transmission-enable signal from an AND gate 19 is stopped and the terminal equipment A stops the use of the line. Then the line control section 10 generates a data transmission request signal of a terminal equipment B, which outputs a data signal corresponding to it. Thus, even if a fault takes place while the terminal equipment uses the line, since the line is not occupied by the faulty terminal equipment and other terminal equipments use the line, the restoration of the line is executed quickly.
